Zorluk: OrtaTroubleshooting Windows OS Startup and Boot Errors

A user modified partition settings on a legacy MBR-based Windows 10 system, resulting in a startup failure with error code 0xc000000e indicating missing or corrupted Boot Configuration Data. A help desk technician boots the computer into the Command Prompt within the Windows Recovery Environment (WinRE). Which TWO commands should the technician execute to locate installed operating systems and reconstruct the boot database? (Select TWO.)

  1. bootrec /scanosCevap
  2. bootrec /rebuildbcdCevap
  3. C
    bootrec /fixmbr
  4. D
    chkdsk C: /r

Cevap

The technician must execute `bootrec /scanos` to identify Windows installations missing from the Boot Configuration Data and `bootrec /rebuildbcd` to reconstruct the BCD database.
The correct steps involve using `bootrec /scanos` to detect installed Windows instances missing from the boot configuration and `bootrec /rebuildbcd` to rebuild the Boot Configuration Data store, allowing the OS entry to be restored.

Adım Adım Çözüm

1
Identify the cause of the boot failure
Error 0xc000000e points to missing or inaccessible Boot Configuration Data (BCD).
Understanding the error code narrows the required repair utility down to BCD-specific commands.
2
Execute the boot scanner utility
Running `bootrec /scanos` checks drives for valid Windows installations not referenced in the BCD.
Verifies that the operating system files are detected before modifying boot entries.
3
Rebuild the boot configuration store
Running `bootrec /rebuildbcd` prompts the technician to add detected OS paths into a fresh BCD database.
Restores proper boot entry mappings so Windows can initiate startup.
